Answer 3

You're given the hydronium ion concentration and you're given the pH, which are really just two different ways of saying the same thing. Let's focus on the pH because it makes it easier to tell whether a solution is acidic, basic, or neutral.

A pH of 7 is considered neutral.

If the pH is less than 7, the solution is considered acidic. The lower the pH, the more concentrated the hydronium ion becomes, and the more acidic the solution.

If the pH is greater than 7, the solution is considered basic. The higher the pH, the less concentrated the hydronium ion becomes, and the more basic the solution.

Using this information, which option do you think is your answer?

Answer 4

I would say that based on this information, it would probably have to be, weak acid?

Answer 6

It's a weak acid. Remember your pH scale. 7 is nutral, below 7 is acidic and above 7 is alkiline.

Answer 7

So 6 would be a very weak acid. :)

Answer 8

Yay. Thank you so much!

Answer 9

No problem. :)

Answer 10

Yes weak acid is correct!
